Title: Improvements in or relating to thermographic methods of and apparatus for copying graphic originals
Inventor: KOBLER ALFRED
IPC: B41M5/26
Filed: 1961-01-04
Abstract: 975,804. Thermographic copying. OZALID CO. Ltd. March 20, 1962 [Jan. 4, 1961; Feb. 23, 1961], Nos. 306/61 and 6623/61. Heading G2C. A graphic original is copied thermographically by exposing to infra-red radiation the original in face contact with an intermediate sheet coated with an intermediate sheet coated on its other face with a distillable or sublimable substance and in contact with a copy sheet, whereby transfer of said substance takes place imagewise to form a latent image on the copy sheet. Preferably this latent image is made visible by dusting it with a pigmented powder which is subsequently fixed on the copy sheet. Typically the volatilizable coating material is a mixture of diphenyl and diphenyl oxide with or without heplane, decane or diethylene glycol; chlorinated diphenyls; dimethyl, diethyl, dibutyl or di(methyl glycol) phthalates; dibutyl sebacate; butyl stearate; methyl abietate; methyl dihydroabietate; naphthalene; naphthols; 2: 3-dihydroxynaphthalene; o-nitrodiphenyl; solid chlorinated naphthalene; or ammonium chloride, and the developer may be a finely divided carbon black pigment mixed with small galss balls as a carrier. As shown the original is inserted at 17 and fed around a cylinder 11 where it is exposed either directly or by reflex action to infra-red sources 2, 3, the intermediate sheet 4 is coated with the volatile material in trough 12 by transfer rollers 19, 20, and the image formed on copy sheet 7 developed by passage beneath developer hopper 13 and fixed by infra-red heater 14. Alternatively the latent image on the copy sheet may be passed over a wet roller to moisten the non-image areas, andthenover a greasy inkroller, the resulting greasy ink image then being transferred to either paper or a lithographic plate.

Title: Lyophilic biologically active substances and process of producing the same
IPC: A61K35/16
Filed: 1935-01-04
Abstract: <PICT:0450145/III/1> Biologically active preparations in a dry state, from which a liquid product may be readily made by addition of water, are obtained by rapid freezing of a liquid or semi-liquid substance, e.g. a serum, by indirect contact with a refrigerant and sublimation of the ice from the frozen material, without previous crushing or comminution, by application of a high vacuum.  The serum &c. is rapidly frozen, e.g. by addition of successive thin layers upon the interior of a flask 1 exposed to a low temperature and the flask is then connected, as by a tube 3 and rubber gaskets 4, 6 with a condenser flask 5 immersed in a freezing medium 8 and connected at 9 to a high vacuum.  The dried solid material may be kept from contact with air by sealing in a container, e.g. such as described in Specification 450,147.

Title: Boiler cleaner
IPC: F28G3/16
Filed: 1924-01-11
Abstract: 219,592. Smith, H. P., (Diamond Power Specialty Corporation). Jan. 11, 1924. Cleaning, fluid pressure processes for. - In a rotary blower unit with valve control for cleaning boilers the valve is directly operated for opening and closing from the same spindle which rotates the jet tube. The valve D controlling the supply of steam to the jet tube is opened by the first part of the rotation of the worm shaft F, the worm. wheel G<1> on the jet tube being held stationary by a locking-lever H<2> and acting as a nut for the worm G. simultaneously with the contacting of the shoulder F<1> on the worm with the casing F<2>, the locking-lever is released and the jet tube is rotated, no further opening of the valve taking place. On reversing the rotation, the jet tube is first rotated back to its normal position, the shaft F being prevented from axial movement by the locking-lever engaging the surface of the worm wheel G<1>. In a modification, Figs. 3 and 4, the valve K is opened by the first part of the rotation of the wheel L. which acts as a nut to the screwed valve shaft K<1> which is prevented from rotation by a spring pawl M<2> engaging a slot M in the shaft. An incline N at the end of this slot releases the pawl so that the shaft is rotated and rotates the jet tube through sliding dogs S, the hand wheel and shaft being locked by dogs O. On reversing the rotation of the hand-wheel, another pawl M<1> prevents rotation of the shaft which then is slid axially to close the valve. An adjustable sleeve-valve J<3> also aids in controlling the entry of steam to the valve casing.

Abstract: 710,671. Rotary engines or pumps. STRAATVEIT, N. N. Jan. 11, 1952 [Jan. 12, 1951], No. 932/52. Class 110(2) A gyratory piston 10 moves between fixed inner and outer walls 4. 5, all points of the piston moving in circles, the piston being rigidly connected to means adapted to transfer forces to or from the piston. The transfer member or members 20 moves freely in an opening in a wall, the opening being sealed to prevent leakage of the working, medium between inlet and outlet sides of the working chamber 6. In Fig. 2 a fixed partition 9 extends through a slot in the piston. A driving (or driven) shaft 17 and an eccentric 18 drives the piston 10 through the disc 20 which extends into a slot 25 in the partition 9. To prevent leakage through the slot 25, close-fitting links 26, 27 fill the slot as the piston moves downwards and one end of the link 27 seals a part of the containing chamber 31. Other types of linkage may be used for sealing purposes. In another form, Fig. 6 (not shown), the seal comprises a radially moving spring-pressed bar which may have a roller on its outer end. Fig. 7 shows another type of seal in which, a tongue 38, on the piston, has a'cylinder 39 which is pressed against the wall of the chamber 31. The tongue may extend from the outer wall 5 into a chamber within the disc 20. Fig. 9 shows a pump or motor provided 'with spokes 42 which transmit the forces between the shaft 17 and piston 10 through an eccentric 18. The spokes extend through slots 43. In Fig. 10 the sealing means for each opening in the wall 4 comprises a slider 44 containing slippers 45 which co-act with a spoke 42.

Title: Vehicle speed sensor for skid control system
IPC: G01P3/50
Filed: 1974-01-09
Abstract: 1402408 Antiskid braking systems NISSAN MOTOR CO Ltd 9 Jan 1974 [22 Jan 1973] 00935/74 Heading F2F [Also in Division H4] A vehicle speed sensor comprises a Doppler radar system operatively mounted on the vehicle to produce an electrical signal having a voltage corresponding to the speed of the vehicle, when connected to a power source, and a first switch operative to effect said connection when the vehicle brake pedal is depressed. The sensor is applied to a skid control system in which the brake cylinder pressure is modulated either in accordance with the slippage of the vehicle wheels or with the deceleration thereof. As described, a Doppler radar system 10, Fig. 1, comprises a signal generator 11 which is coupled to an aerial 12 through a circulator 13 and which is connected to a battery 18 when a first switch 17 is closed by depression of the brake pedal 16. Echo signals received by the aerial 12 are coupled through the circulator 13 to a mixer 14, which also receives an input from the signal generator 11. Doppler signals from the mixer 14 are processed in a frequency/voltage converter 19 to provide a signal having a voltage proportional to the vehicle speed. This signal may be connected by a second switch 21 to a brake pressure controller 20. The switch 21 is associated with an actuator 22, which receives inputs from junctions A (output from the switch 17), B (output from the mixer 14) and C (output from the converter 19). Closure of the switch 21 only occurs in use if there is no output at any junction (brake pedal not depressed, system functioning normally) or if there is output at junctions A and B or A and B and C (brake pedal depressed, system functioning normally, vehicle at rest or in motion). Otherwise, the actuator operates an alarm 23, indicating that the system is functioning abnormally. A circuit for the actuator 22 is shown in Fig. 2 comprising an OR gate 31, which receives inputs from the junctions A, B, C, that from the junction B being coupled through a D.C. amplifier 30, and an AND gate 33 which receives input from the junction A and amplified input from the junction B. The output terminal Q of the gate 33 is connected through a resistor R 5  to the battery 18 and to one input of an OR gate 34. Output from the gate 31 is inverted in an inverter 32 comprising a transistor TR, the collector terminal P of which is connected to the battery 18 and to the other input of the OR gate 34. Output from the gate 34 is developed across a resistor R L  at a junction J 2 .
